New version highlights a "Top Charts" section that has a Top Free, Top Paid, Top Grossing, Top New Paid, and Top New Free.

An editor's choice list will highlight the apps favored by the Android team.

"Related apps" will help users find apps that are similar to the one they're looking at.

Android Market will now be available in 99 more countries, bringing the total to 131 countries

The market will now allow content filtering.

The size limit on apps will soon be increased from 50MB to a masive 4GB.

Developers can now manually choose any device to blacklist

These new updates are pretty thoughtful, and should help developers most of all. Often apps get bad ratings just because users downloaded them to phones they weren't meant to work on; now, developers will be able to blacklist phones to keep this from happening.

"Top" lists and "Editor's Choice" make it easier to wade through the junk. Expansion of the Market to new countries makes the entire enterprise more lucrative. Finally, the expansion of size limits is the biggest news of all. With GBs instead of MBs to work with, developers will be able to craft beautiful apps that take full advantage of newer phones' increased processing powers and screen resolutions.

All in all, these are huge updates! Not only do they address quality control across all apps, but they also expand the reach of the Android Market.
